Game not working in fullscreen mode (OS X)
War of the Overworld can't run in fullscreen mode on OSX 10.11.2. Right after start game seams to trying run in fullscreen mode, but window blinks several times and runs in windowed mode. Using CMD + F or using window controls to go to fullscreen doesn't work. Game working in windowed mode very well.
Logs from system console (game is running in main menu and I trying to run fullscreen):
04/01/16 18:53:48,142 kernel[0]: process WFTO[1037] thread 128304 caught burning CPU!; EXC_RESOURCE supressed due to audio playback

Seems it could well be an issue with your OSX version:
